Burnishing and Working Metal


Metal has long since been a critical building material for civilization ever since the earliest copper and iron tools, and today, massive industries exist for the mining, refining, and retooling of all sorts of metals into various forms, shapes, and alloys for nearly every other industry out there. There are many different ways to modify metal for different purposes, and some involve more invasive methods on the metal than others. A piece of metal may have a chipless machining method applied to it, for example, which refers to processes that do not remove material from the metal while machining work is being done on it. A chipless machining method can be very useful for metals, such as casting, forging, rolling, welding, and riveting, among others. Aside from a chipless machining method, another way to treat metal is through burnishing it for a better surface on the metal. What is a burnishing tool used for? Is diamond burnishing an option? What other methods of precision metal finishing are out there for expert metal workers? These are some questions that any industry worker today should ask when setting out to perform a job on metal, whether a chipless machining method, burnishing, or more.

The Materials

Quite a few different metals, alloys, and even diamond are out there for precise work such as roller burnishing or more. Manufacturing is huge; it contributes some $2.7 trillion to the American economy, so of course innovations for metal working and ways to cast or burnish metal are always essential for continued growth in this sector. In fact, recent data shows that in the manufacturing sector alone, some 256,363 firms exist, and all except about 3,626 of them are smaller businesses, having under 500 employees, so these small businesses will want to offer the best possible products for the market, and that means having the right metal working processes to work with. In general, machining operations for metals are split into three broad categories, with those being turning, drilling and milling, and quite a few different alloys may be created with these processes. Some alloys have just the right combination of metals so that they can endure very high temperatures, like those used in industrial furnaces or engines, while others are used for undersea pipes and therefore must endure constant exposure to salt water. Some metals are used in chemical processing and must be able to withstand the chemicals that they carry every day during work.

Aside from chipless machining methods, burnishing diamonds or metals can be done to give these materials a more attractive surface, and burnishing a material may be easier and simpler than some may realize. Often, using a handheld burnishing tool is all that is needed, and if the right settings are used, then the tool’s blunt end can be applied to the metal or other material and use it as though engraving that material, covering it all until the job is done. This will result in an attractive, final look that the worker, or whoever commissioned the burnishing job, will like. The finish should be smooth and shiny, and appealing to look at. Since no material is removed, this may also qualify as a chipless machining method for metals.
